[0002] Ultrapure water, also known as UP water, is often used in the integrated circuit industry for cleaning semiconductor raw materials and utensils used, preparing photolithography masks and as a water vapor source for silicon wafer oxidation. The generation of ultrapure water is achieved by directly connecting an ultrapure water machine to tap water for filtration. An ultrapure water machine uses pretreatment, reverse osmosis technology, ultrapurification treatment and post-treatment to almost completely remove the conductive medium in the water, and remove the undissociated colloids, gases and organic matter in the water to a very low level. The most important part of an ultrapure water machine is the filtration mechanism, which plays an extremely important role in ultrapurification and filtration of water. When in use, tap water is discharged directly into the filtration mechanism through the tap pipe for treatment. In this process, the tap water will contain a lot of water impact force, which will rush directly into the filtration mechanism, which will inevitably cause damage to the filtration mechanism.

[0008] Preferably, the outer surface of the internal threaded ring, the outer surface of the fixed cylinder, the outer surface of the processing cylinder, and the outer surface of the fixed column are all fixedly sleeved with a rotating ring.

[0009] To summarize, the present application includes the following beneficial technical effects: when external water enters the treatment cylinder through the water injection head, it will flow in the spiral flow channel, then flow downward in a spiral manner in the spiral flow channel and enter the interior of the first connecting head, and finally flow to the interior of the filter mechanism body through the first connecting head.
